Stainless Steel Jaw Couplings

Stainless steel jaw couplings as a special material flexible coupling, occupy an important position in the field of mechanical transmission.

Claw coupling (also known as plum blossom coupling) mainly consists of three parts: two metal half coupling discs with protruding claws and an elastic element. The standard model usually uses 45 steel as the claw plate material, while in corrosive environments or special load requirements, stainless steel material is used.

Stainless steel claw discs have three significant advantages:

1. Excellent corrosion resistance: can resist harsh environmental erosion such as moisture, acid and alkali, and extend the service life of equipment
   

2. Higher strength characteristics: Compared to ordinary steel, stainless steel provides better mechanical strength while maintaining toughness
   

3. Health and safety standards: meet the hygiene requirements of industries such as food and medicine, and avoid pollution risks

The intermediate elastomer is usually made of polyurethane or engineering rubber, providing vibration absorption and deviation compensation functions. The elastomer is designed in the shape of plum petals (commonly 4-8 petals) and achieves flexible transmission through compression deformation. Its lifespan can usually reach 10 years.

Application Fields

1. Food and pharmaceuticals: filling equipment, packaging machinery
   

2. Marine engineering: ship pumps, deck machinery
   

3. Chemical industry: pumping system for corrosive media
   

4. Precision manufacturing: CNC machine tools, semiconductor equipment

Stainless steel jaw couplings demonstrate irreplaceable value under special working conditions through their unique material advantages and structural design. Proper selection and use can significantly improve system reliability and reduce full lifecycle costs, making it an important component of modern industrial transmission systems.
